Introduction In our earlier blogs, we discussed the prelocation using the Time Domain Reflectometry (TDR) method, for faults like low resistance, short circuit, ingress of moisture, and open circuit faults. Insulation failure / High Resistance faults cannot be determined using a low voltage source of a TDR or Prelocator instrument. In Mid Voltage (MV) to …

In the previous blog post, we discussed how electrical utilities are using underground cables to gain a higher degree of reliability. However, underground cable faults can lead to a long downtime, which can further lead to a major revenue loss for electricity utilities. We also discussed the various causes of cable faults and the different …
